Observational learning is the learning that occurs through observing the behavior of others. This form of learning does not need reinforcement to occur; instead, a model animal is required. While the model may not be intentionally trying to instill any particular behavior, many behaviors that are observed are remembered and imitated. The domestic dog is a social species and its social dependency makes it aware of the behavior of others, which contributes to its own behavior and learning abilities. There is, however, ongoing discussion about how much, and how, dogs can learn by interacting with each other and with people.
Lindsay says of this study, "Schilder and Van der Borg (2004) have published a report of disturbing findings regarding the short-term and long- term effects of shock used in the context of working dogs that is destined to become a source of significant controversy ... The absence of reduced drive or behavioral suppression with respect to critical activities associated with shock (e.g., bite work) makes one skeptical about the lasting adverse effects the authors claim to document. Although they offer no substantive evidence of trauma or harm to dogs, they provide loads of speculation, anecdotes, insinuations of gender and educational inadequacies, and derogatory comments regarding the motivation and competence of IPO trainers in its place." 
With more than 25 years of experience, renowned dog behavior expert and New York Times best-selling author Cesar Millan is one of the most sought-after authorities in the field of dog behavior and rehabilitation. In March 2014, Millan brings his unmatched canine abilities to communities terrorized by unruly hounds in Nat Geo WILD's new series "... See full bio »
The principle behind using a crate for housetraining is that dogs are very clean creatures and don’t like a urine-soaked rug in their living spaces any more than you do. It’s important that the crate is the right size—just large enough for the dog to lie down, stand up, and turn around. If it is too large, the dog will feel that it’s OK to use one corner for elimination and then happily settle down away from the mess. Many crates come with partitions so you can adjust the size as your puppy grows.
The process is the exactly same for older dogs as it is for puppies; prevent accidents from happening by using baby gates and a crate if possible, create a predictable schedule, learn to recognize your dog’s potty signals, accompany your dog outside and immediately reward for all outdoor elimination, properly clean any accidents and supervise your dog until you’re sure that he understands the rules.
In considering the natural behaviours of specific breeds of dogs, it is possible to train them to perform specialised, highly useful, tasks. For example, Labrador retrievers are the favoured breed for the detection of explosives. This is because of a combination of factors including their food drive which enables them to keep focused on a task despite noise and other distractions. Most working breeds of dogs are able to be trained to find people with their sense of smell (as opposed to their sense of sight). Cocker Spaniels are able to be trained as part of a termite detection team. Their relatively small size enables them to fit into small spaces, and their light weight allows them to walk on areas of ceiling which would be dangerous to anything heavier. In fact, although unusual, termite detection dogs are much more reliable at detecting termites than humans who rely on a basic system of tapping and listening. Because of their ability to learn signals by sight and for their energetic and athletic natures, German Shepherds are able to be trained for work alongside search and rescue teams and human apprehension teams.
On a side note, a puppy’s mother can actually do a lot of the potty training for your dog. I know of several reputable breeders who tell me that the mother dog trains their pups not to eliminate in their nests. From the moment a puppy is born its mother is teaching it that the NEST is the place where it eats & sleeps. One of the first rules Mama Dog starts to teach her pups is NO peeing or pooping in the family nest – That’s Disgusting! And she makes them follow her outside.
Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
